AUGUST KRASTIN, OF CLEVELAND, OHIO.

SPEED-GOVERNOR FOR EXPLOSlVE-ENGINES.

SPECIFIGATION forming part of Letters Patent No. 674,034, dated May 14, 1901.

Application iiled June 14, 1900.

To @ZZ whom, t may concern,.-

Be it known that I, AUGUST KRASTIN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Charge-Mixing Apparatus for Explosive-Engines, of which the following is a specification.

My invention relates to improvements in apparatuses designed for feeding the charges for hydrocarbon explosive-engines; and the objects of my improvement are to provide simple, efficient, and easily-manipulatable means for this purpose, which furnish for all condition (loads) the requisite charge thoroughly mixed and of the proper explosive quality. I attain these objects in an apparat-us constructed substantially as shown in the accompanying drawings, in which- Figure l represents a vertical longitudinal sectional view of such apparatus in connection with the valve end of an explosive-motor cylinder. Fig. 2 represents a cross-sectional view of same on line sc 93. Fig. 3 is an inner face view of a part thereof detached, and Fig. 4 is a front end View of said apparatus.

Like letters of reference denote like parts in the drawings and specitication.

In the drawings, A designates the cylinder, B the piston, and Othe inlet-valve, of an explosive-engine. The port a leads to its exhaust-valve. (Not shown.)

The charge-supplying contrivance comprises, substantially, the casing D, upon and within which are mounted the barrel E and sleeve F, the piston G, which snugly tits said barrel, and the lever H, which permits the shifting of said sleeve and piston sim ultaneously.

At b the casing D is adapted t'or connection with the inlet-valve cage I, with which cage the former is arranged in open relation, as shown in Fig. l. The relative position of casing to valve-cage may vary to suit particular engine constructions without departing from the nature of my invention.

In the fore part of the casing is slidingly arranged the sleeve F. Said sleeve has an internal partition c. Outside of said partition a link d has pivoted connection with said sleeve,

ver H, the latter being pivoted between the brackets ff-of casing D, as seen in Figs. l and 4.

On top ofthe sleeve F is provided an arm g, which affords adjustable screw connection with the piston-rod 71,. In the lower inner side of said sleeve are a plurality of laterallyarranged ports 'L' t' t', all of which ports may be set in open relation with the openingj of the casing, or by shifting the lever H from the position as shown to that indicated at k and 7a one is enabled to set only two or one of said ports in communication with the openingj. Said opening is preferably covered with a screenj to prevent dust from entering said ports or sleeve. The barrel E is arranged on top of the casing D. A depending portion Z 0f said barrel extends through an opening of said casing into the interior part thereof, as seen in Figs. l and 2. The front end of said barrel is provided with a removable plug m to enable insertion of the piston, and inside the plug is an adjustable gland n, screwed up against the packing o for the purpose of establishing a liquid-tight joint for the pistonrod, which has sliding contact in and through said packing. A feed-pipe p intersects with the barrel at or near the plug` end, as shown in Figi. In said feed-pipe is provided a needle or stop valve q for control of the flow of the liquid fuel thatvis conveyed to said barrel.

In the bottom of the barrel (respectively in its depending portion Z) there are a plurality of perforations r. Said perforations present such diminutive capacity as to require an actual suction of the main piston in order to establish a flow of liquid through said perforations. Such conditions must necessarily effect a thorough mixture ot` the liquid fuel with the intlux of air.

The barrel E and sleeve F are relatively so positioned or adjusted that the piston exposes as many perforations as a certain influx of air will require in order to effect a properlyproportioned explosive mixture. When air is drawn through all the ports, then the combined capacity (area) of all the perforations is also available to furnish the necessary liquid fuel for a full charge of an explosive mixture. In shifting the lever to a position as which link in turn connects with arm e of lel indicated at 7c then the outer port of the sleeve IOO would be covered by the easing and the inner perforation or perforations of the barrel by the piston G. Thus less air would be drawn in; but also less liquid fuel Would be available for such diminished quant-um of air, and if the lever is set in a position as indicated at lo then air can only enter through the inner port Vand liquid fuel only through the outer perforation or perforations, which in this instance would furnish the smallest charge for the cylinder, but yet the same would be composed of the requisite proportions to render it comparatively efficient.

From the foregoing it can readily be understood and seen that by supplying the liquid fuel in 1finely-subdivided state a thorough mixture of air and fuel can at all times be effected, and by adjusting the air and fuel supply the proper proportions of air and liquid fuel can and Will be maintained to furnish an explosive mixture in varying charges.

In the side of the casing and at or near the air-inlet glasses s are inserted to enable observation of the commingling process of the air With the liquid fuel.

What I claim, and desire to secure by Letters Patent, is

In explosive-engines the combination With 'inlet-valve cage of a casing arranged in open relation with said cage, said casing having a side opening, a perforated, partitioned sleeve registering with said opening, a fuel-supply barrel With a perforated portion extending into said casing,- a piston located in said barrel and arranged to control the perforations therein and suitable means for moving said sleeve and piston in unison all constructed and arranged substantially as and for the purpose set forth.

In testimony whereof I aflix'my signature 4o in presence of two Witnesses.

AUGUST KRAS'IIN.
